SUMER Re-Analysis: The Global Scale

- Ne VIII blue-shift in the CH not isolated only to network vertices, 65% lies to the cell-interior side of the boundary. NO obvious correlation of the blue-shift pattern to that of the gross chromospheric network.- Cell interior emission of C IV and Ne VIII is ~40% less than in the QS. -The vast majority of strong Ne VIII outflows lie in locations of locally unbalanced magnetic fields.

-Large portion of the CH cell interiors (25%) contains C IV blue-shifts and they are closer to cell boundaries than cell centers - only 10% lie within 2Mm of a boundary. QS contains very few CIV blue-shifts (5%), but they neighbor network vertices.

-92% of the C IV blue-shifts in the CH lie “under” Ne VIII blue-shifts.

- Magnitude of the blue-shift (CIV & NeVIII) is tied to the amount of unbalanced magnetic field present.The key to understanding these relationships lies in understanding the C IV pattern and how it ties to Si II and Ne VIII

The relentless emergence, advection and eventual destruction of magnetic flux on supergranular scales is responsible for the mass loading, heating and initial acceleration of plasma at the base of the solar corona and wind.

The local field conditions control the rate and scale of the energy release.

The global magnetic field topology controls how the energy is released and utilized by the plasma.

Solar wind initiation and atmospheric plasma heating CAN be performed with ONE single process. “Spicules” are the basic building block of that process.

The smaller scale magnetic unbalance (-20Mm) controls the ferocity of the reconnection and the resulting energy release.

The global magnetic topology of the plasma acts as the “thermostat” - controlling the energy balance between kinetic and thermal dominance.

Coronal dimmings [transient coronal holes], CMEs and POSSIBLE secondary acceleration from following fast spicular wind streams..........TBD

The Laundry ListWorking on the “if it walks like a duck...” principal we have seen that the spectroscopic, imaging and wave signatures observed are all consistent with the ubiquitous driving of the solar plasma by magnetoconvection-driven reconnection.
